Need Otari MX-5050 NAB Adapters

I'm on the hunt for a pair of Otari MX-5050 BII NAB Adapters. What are my options as I'm not seeing very much on a Google search.

Are these unique to the MX-5050?

Pretty much, yes they are, I think. You`ll find them on E-bay. Sometimes outrageously high, but if you are patient you can get them for a decent price. Good Luck!

The short answer is no, they don't need to be Otari-specific. There are other company's that made/still make the screw down NAB adapters for non-locking
Trident reel tables.

The ones used by/for ATR/Ampex, Crown, Scully, and similar machines will work just the same. Jcorder has them, but are pricey, look here:

http://shop.j-corder.com/category.sc?categoryId=5

Used examples of the genuine Otari NAB's are always on Ebay, along with the others I listed off the top of my head,.. often as a pair for 50$ and under, or as much as 100$ or more each. You have to shop for the best prices, make sure they are returnable if they are purchased used, as they can be broken or worn out to a point where they wont lock on to the shaft.

Search for Darklab hubs, they offer the some ones they make for JCorder direct from them. Be wary of the ones made in Europe, the knock off versions, I have heard bad things about them from others, especially among the Studer/Revox users that bought them.

Those do NOT work on a earlier MX5050 which does not have the Trident locking spindle
!! Conversely - the MX5050's won't work on the 55N due to the spindle lock.

But they will work on an MX-5050 equipped with Teac reel tables as described in the link I included in my earlier post.

Anyone know of the ones that allow height adj. by single Phillips screw on the table (like the 4300's) will work on 5050's THAT'd sure be nice !!__

Perhaps Gustavoa would know since he has done this type of modification on the MX-5050s that he offers. I gather that this would provide adjustment similar to what is available on Pioneer RT-909s.

I know about the reel table swap as well, have never investigated it to the point of using tables with center adjust for table height. While if you already have the tables or a junk machine to take them off its easy. Some are next to nothing from sellers that are parting machines out, but I would just break down and get a set of the screw down type locking NAB's. I have a few sets here and love them much more than the ones that do not lock down, and overall they are far more secure and pro feeling/substantial than the ones that a locking trident use.

Make sure to get the table shims as well when you get the screw down NABs., they compensate for reel height. That is the ONLY advantage to the locking trident type NAB, many don't require the shims. Other than that I would get the pro locking ones and shims, your set. FWIW, I never use that center screw adjuster for table height UNLESS:

A: The deck has been shipped, packed improperly and fell on it's face, pushing the tables in on their shafts/ if not bending-breaking them right off entirely,


B: Either the machine was shipped with them set wrong, from the factory, some one had the hub off and didn't set the depth correctly...the reel table/NAB hub-Reel-Tape assembly should be set perfectly with center in-out adjustment in the half-way position. I use just the inside Allen screws or similar fasteners that position/fasten it on the motor shaft.

C: A previous owner let it fall on it's face, again pushing the reel tables in or adjusted them for a NAB hub type that needed the shims/odd thickness-warped reel. Refer to be for proper set up.

In case A or C the trident can be cracked, bent or broken off. Pot metal can not be soldered or welded. The smooth no locking trident reel tables I have here are ,made os steel and can be. They are also thicker and more substantially made, so bending or breaking them in an accident

I like the solid thick trident shafts, no flex, substantial in feel and quality. Truth is if you use the deck on its back on a tabletop or in it's rolling cart mounted with rack flanges you can use any NAB set up for tridents locking or not.

REW-FF-Play at any speed, the reel and tape weight will keep them planted on the hubs and tape on/on the guides. Don't try that in any other position, unless you want a 1/4 to 1/2 mile or more of tape all over the room, reels flying around the room like the Jupiter 2 from Lost In Space... or aiming for your head, stuck in a wall...

There are several on Ebay right now for little$$$..if you don't want the high $$$ ones. I like the pretty ones. A Red, Silver or Blue anodized pair will make any reel to reel -type-color-style look great mixed with B is that it holds smaller reels on the spindle trident 5" 7" etc. Just place the reels on then lock the NABS on top with the screws. Easy as pie. Another consideration is if you buy another machine without licking tridents, it will need to be converted as well, and we all know reel to reels multiply like cats and rabbits in heat..

Thanks for the information, I will hawk ebay for a used set.

Not 100% sure what I need based on all of the above but the MX-5050 I purchased is a early 1985 unit (SN 33). Still waiting for it to arrive.

You need 2 of these or similar, just type in NAB hub into Ebay search all categories:

http://www.ebay.com/itm/Otari-TW-670...4AAOSw44BYcZfP

or:

http://www.ebay.com/itm/VIF-Intl-ree...UAAOSwZQRYc5qX

You also 2 of these to set reel height: (left and right)

http://www.ebay.com/itm/2x-Otari-ree...3D351903263617

I use google search for each item with for sale near me in the subject/search box. Look around for best prices, deals are out there. I like the Otari brand best of the OEM offerings, the second ones I listed would be my second choice if I could not find the first ones.

Yea, they can be reel proud of those rubber sheets. I bought some scrap rubber and made my own 1/16 in thick. They seem to work OK. Not the prettiest, but come out to about a buck each.

I can't post a ebay link from this computer but there is a set of NAB hubs that the repair shop says will work on my MX-5050.

They are listed as VINTAGE VIF International Reel to Reel NAB Hub Adapters for $79.99

Can anyone verify if this set will work on my MX-5050?

Thanks
Dennis

The VIF adapters work best for my money. There are two sizes of Otari adapters. The difference is knob size, basically. Both will work on all versions of MX5050. Neither have worked as well as the VIFs.

Dennis, get those VIF hubs at the buy it now price. They will work just fine. Kenny's got your deck running. It had a bad 7403 TTL logic chip. Luckily I have an old parts bin full of TTL chips.

Great looking forward to using this machine. I bought the VIF Hubs yesterday.
